The Helix Nebula is one of the most well-known and commonly photographed planetary nebulae because it resembles the "Eye of Sauron." It is also one of the closest bright nebulae to Earth, located approximately 655 light-years from our Solar System.
You may not know what this particular nebula looks like when reading its name, but the Hubble Space Telescope has taken some iconic images of it over the years. And almost certainly, you'll recognize a photograph of the Helix Nebula, shown below.
Like many objects in astronomy, planetary nebulae have a confusing name, since they are formed not by planets but by stars like our own Sun, though a little larger. Near the end of their lives, these stars shed large amounts of gas in an expanding shell that, however briefly in cosmological time, put on a grand show.

Eleven years after United Launch Alliance CEO Tory Bruno partnered with Blue Origin to create a new rocket engine, he’s joining Jeff Bezos’ space venture as the president of Blue Origin’s newly created National Security Group.
The move could signal a major shift in the commercial space race as Kent, Wash.-based Blue Origin revs up its competition with SpaceX. Bezos welcomed Bruno to his company on social media, and Bruno told Bezos that “we are going to do important work together.”
In Friday’s announcement of the change, Blue Origin said Bruno would report to CEO Dave Limp. “We share a deep belief in supporting our nation with the best technology we can build,” Limp said in a post on X. “Tory brings unmatched experience, and I’m confident he’ll accelerate our ability to deliver on that mission.”
Bruno, 64, led ULA for 11 years following a 30-year career at Lockheed Martin. Not long after taking the reins at ULA in 2014, Bruno sat beside Bezos to announce a close collaboration on the development of Blue Origin’s BE-4 engine, which is used on ULA’s Vulcan rocket as well as Blue Origin’s orbital-class New Glenn rocket.
United Launch Alliance is a joint venture between Boeing and Lockheed Martin. Last year, there were rumors that ULA was the subject of acquisition talks, perhaps involving Blue Origin or Sierra Space, but so far those rumors haven’t panned out.

The form and size of a herb garden is determined by the interest these plants hold for the individual. It can be a tiny border of commonly used culinary herbs such as mint, parsley, sage and thyme or an elaborate garden designed to house a wide collection of herbs. Many plants could legitimately be included in one of these large […]
